Milne-Shaw seismograph no.1, designed and constructed by John Johnson Shaw, 1914, based on an original design by John Milne. The instrument, which has a horizontal pendulum and electromagnetic damping, was tested at Bidston Observatory, near Liverpool, and in 1918 was transferred to the University Observatory at Oxford.

Seismograph, marked no. 2, designed by Omori Fusakichi for the Earthquake Investigation Committee, Tokyo, Japan, 1898. It combines a horizontal pendulum mechanism with an auxiliary inverted pendulum, and employs a smoked-paper recording system. The instrument was constructed in Japan, and in 1910 displayed at the Japan-British Exhibition, White City, London. Afterwards it was transferred to Eskdalemuir Observatory, Dumfriesshire, Scotland and operated intermittently until 1925, when the observatory’s seismological programme, administered by the Meteorological Office, was transferred to Kew.
